I have used the search function and could find no definitive answer. The two sets in question are the Pioneer TS-A1605C and Infinity Primus PR6500cs . I found both at a similar price. I chatted with an advisor to get clarification on fitment; of course they'll both need the sahr6 brackets. Sadly, in an effort to keep costs down, they'll be running only off a HU (most likely 22rms/50max - I haven't decided model yet. recommendations welcome). They will be paired with an MTX Thunder 202 and either a single MTX TN10-04 , Kicker C104 , or RF R1S410. I don't have a problem installing the tweeters in the sail, if need be. This is my budget, family friendly build. At this point, ANYTHING is better than stock paper. Thank You for your input.
